Montech today unveiled the Beta 2 line of mainstream ATX 3.1 power supplies. These PSUs are designed to meet ATX 3.1 and PCIe 5.1 CEM specifications, providing mainstream-thru-performance segment gaming PC builds with a modern PSU architecture. These come in four variants based on output, 550 W, 650 W, 750 W, and 850 W. All four offer 80 Plus Bronze-rated switching efficiency. All four models come with fixed cabling, which comprises individually-sleeved wires for each cable.

The PSUs feature single +12 V rail design, DC-to-DC switching, and most common electrical protections. All four use 120 mm hydro-dynamic bearing fans, and a Japanese-made main capacitor. All four models come with 24-pin ATX and two 4+4 pin EPS connectors. The 550 W, 650 W, and 750 W models come with two 6+2 pin PCIe power connectors (which meet ATX 3.1 excursion specs); while the 850 W model offers a 450 W-rated 12V-2x6 connector besides two 6+2 pin PCIe power. Montech is backing all four models with 5-year warranties. The 550 W model is priced at $49.90, the 650 W model at $59.90, the 750 W model at $63.90, while the 850 W model goes for $69.90.
